Transmission Failure problems of the 2010 Hyundai Elantra

When putting the car in park on a incline the transmission fails to hold the car resulting in the car rolling away while unoccupied, I put my 2010 Elantra in park got out of it to get something from the back sseat, the car was on an incline at the time in my driveway. As I reached to open the rear driver side door I hear a loud bang and then I had about a second to look around and then the transmission made a repetitve banging and clicking sound as the car started rolling backwards. I had to open the front driver door and hop in the car while it was moving so I could hit the brake pedal to stop the car. After this I went to a local Hyundai dealer and talked to them about the issue the told me they have seen this before and had to replace transmissions in the cars affected. I bought mine from a used car lot about ten days ago I am taking it back and they are going to attempt to fix the car, however I would like a recall issed so I can take this car to get the problem fixed so I know for sure this is not going to happpen again. . As of right now I have to use the emergency brake to hold the car to be sure its not going to roll away when no one is there to stop it. . This is very unsafe and a google search will confirm that this is an issue with these cars years 2007 till 2010. I can go outside right now and garantee if and stress is created by parking on a slight incline the car will roll away in park. . I showed the dealer that I got the car from this yesterday and it did this 2 out of 3 times that I put the car in park on a slight hill. . . . . Thank you for your time.
